1. A TRAFFIC SIGNAL SYSTEM FOR A PLURALITY OF INTERSECTIONS, EACH INTERSECTION HAVING A PLURALITY OF INTERFERING TRAFFIC MOVEMENTS, VEHICULAR ACTUATED DETECTOR MEANS ASSOCIATED WITH EACH OF SAID TRAFFIC MOVEMENTS, A FULL ACTUATED TIMER AT EACH OF SAID INTERSECTIONS FOR OPERATING GO, CLEARANCE, AND STOP TRAFFIC INDICATIONS FOR EACH OF SAID TRAFFIC MOVEMENTS IN RESPONSE TO ACTUATION OF SAID DETECTOR MEANS BY TRAFFIC IN THE RESPECTIVE TRAFFIC MOVEMENTS, SAID MAIN TIMER BEING OPERABLE TO DISPLAY THE GO INDICATION FOR A PREDETERMINED INITIAL INTERVAL FOLLOWED BY AN EXTENSIBLE INTERVAL, AND SAID TIMER BEING OPERABLE DURING THE DISPLAY OF THE GO INDICATION TO ONE OF SAID MOVEMENTS, AND IN THE ABSENCE OF ADDITIONAL ACTUATIONS OF DETECTOR MEANS ASSOCIATED WITH SAID ONE MOVEMENT DURING SAID EXTENSIBLE INTERVAL, AND UPON ACTUATION OF DETECTOR MEANS IN ANOTHER OF SAID MOVEMENTS, TO EFFECT START OF TRANSFER OF THE GO INDICATION TO SAID OTHER MOVEMENT, SAID MAIN TIMER INCLUDING FURTHER MEANS, OPERABLE DURING THE DISPLAY OF THE GO SIGNAL TO ONE MOVEMENT AND IN RESPONSE TO ADDITIONAL ACTUATIONS OF THE DETECTOR MEANS ASSOCIATED WITH SAID ONE MOVEMENT DURING SAID EXTENSION INTERVAL, TO EXTEND THE GO SIGNAL INDICATION TO SAID ONE MOVEMENT FOR AN ADDITIONAL PERIOD OF PREDETERMINED LENGTH FOLLOWING EACH SUCH ADDITIONAL ACTUATION, A COORDINATING CYCLE TIMER CONNECTED TO SAID MAIN TIMER AT EACH OF SAID INTERSECTIONS, SAID COORDINATING CYCLE TIMER BEING OPERABLE DURING EACH CYCLE THEREOF TO TRANSMIT TO SAID MAIN TIMER A NUMBER OF PULSES CORRESPONDING TO THE NUMBER OF SAID TRAFFIC MOVEMENTS, SAID MAIN TIMER HAVING ADDITIONAL MEANS OPERABLE FOR EACH OF SAID TRAFFIC MOVEMENTS SUBSEQUENT TO THE RECEPTION OF A PULSE FROM SAID COORDINATING CYCLE TIMER DURING A SAID ADDITIONAL PERIOD AND UPON ACTUATION OF THE DETECTOR MEANS ASSOCIATED WITH ANOTHER MOVEMENT TO PREVENT THE START OF A FURTHER ADDITIONAL PERIOD AND TO EFFECT TRANSFER OF THE GO SIGNAL INDICATION TO SAID OTHER MOVEMENT.
